Fluid-Structure Interaction Analysis on Horizontal Wind Turbine Blade
291
Figure 4.2: Wind Pressure Distribution on the Blade Surface Besides, an initial rotational speed of 2.22 revolutions per second is applied along the axis of the turbine.
5. RESULTS AND ANALYSIS During the analysis a number of experiments have been performed by changing the rotor speed or in other word by changing the Tip Speed Ratio. Further the experiment was carried out for both two-bladed as well as three bladed turbines. The figure below shows the results of stress and deformation with the respective TSR and blade numbers. Equivalent Stress
